24AA044T-I/ST

Memory IC Overview

The 24AA044T-I/ST is a 4-kbit (512 x 8) serial electrically erasable programmable read-only memory (EEPROM) manufactured by Microchip Technology. It operates within a supply voltage range of 1.7 V to 5.5 V and supports I2C interface communication with a maximum clock frequency of 1 MHz. The device is housed in an 8-pin TSSOP package and is rated for industrial temperature operation from -40°C to +85°C. It features high endurance, data retention of up to 200 years, and low power consumption with active read currents typically around 3 mA.

Memory IC Feature Summary

• Supports standard and fast-mode I2C bus protocols for reliable two-wire serial communication.
• Provides non-volatile data storage with long-term retention capabilities exceeding two decades.
• Operates across a wide voltage range suitable for diverse embedded system power supplies.

Memory IC Applications

• Industrial control systems requiring parameter storage
• Consumer electronics for configuration data retention
• Automotive modules needing durable memory solutions

Memory IC Procurement Notes

Verify the specific suffix 'I' indicates industrial temperature range and 'ST' denotes the TSSOP-8 package. Confirm RoHS compliance status through official Microchip documentation. Ensure the ordering quantity matches the reel packaging requirements specified by the manufacturer. Cross-reference the datasheet version to confirm electrical characteristics match your design needs.

Memory IC Selection Notes

Select this component when a 4-kbit capacity is sufficient for application data logging or configuration storage. The I2C interface simplifies PCB routing compared to parallel memories. Consider the TSSOP-8 package for surface-mount assembly constraints. Verify that the 1 MHz clock speed meets the system's timing requirements for write cycles.

Memory IC Part Context

This part belongs to the Microchip 24AA044 series of serial EEPROMs. It shares functional similarities with other members like the 24LC044 but differs in operating voltage specifications. The 'T' suffix indicates tape-and-reel packaging, while 'I' specifies the industrial temperature grade. It serves as a compact, low-power memory solution for microcontroller-based designs.

Memory IC Replacement Considerations

Direct substitutes include other 24AA044 variants with different packages such as 24AA044-E/SN or 24AA044T-E/MS. Verify voltage ranges and temperature grades when substituting. Ensure pin compatibility remains consistent across package changes.
